ERROR 44: INVALID UDEF MEM TABLE DATA
This error occurs when an invalid logical address is specified in
the A24/A32 address allocation table.
•
The A24/A32 addresses reserved by the A24/A32 address allocation
table are reserved within the system until
DIAGnostic:BOOT:COLD
or VXI:CONFigure:MTABle 0 is executed.
Interrupt Line Allocation
In a VXIbus system, communication and coordination between a
commander module and its servant module(s) is often achieved using the
VXIbus backplane interrupt lines. During the configuration sequence, the
resource manager assigns interrupt lines to programmable interrupt handler
modules and interrupter modules.
Both commanders and servants can be interrupt handlers and/or interrupters.
The command module which is a programmable interrupt handler, is not an
interrupter. Thus, in systems where the command module is a servant to
another commander, it communicates with the commander through its
Response and Data Low Registers (see the VXIbus System Specification).
The assignment and use of the interrupt lines is described in Figure 2-5 and
with the information which follows.
